All four bills were approved by the GST Council after thorough, clause by clause discussion over 12 meetings held in the last six months.

While the CGST Bill makes provisions for levy and collection of tax by the central government on intra-state supply of goods and services, the IGST Bill does so for inter-state supply.

Similarly, the UTGST Bill is for the union territories like Andaman and Nicobar Islands, Lakshadweep, Daman and Diu and Dadra and Nagar Haveli, which do not have their independent legislative assemblies.

The Compensation Bill provides for compensation to the states for a period of five years for loss of revenue due to implementation of the goods and services tax.

The GST Council has decided July 1 as the date for implementation of the GST.
